a may conce/ai: 'hewn that i, lli-Unie T. Hannions,

a citizen ol3 the United States, residing at Clevelainl, in the county of Cuyahoga and 5 State of Ohio, have invented certain new and useful improvements in Brake-Heads, et which the following is a specilication.

This invention relates to brake heads'and has for its object the provision or' a forged brake head constructed in such manner that it. may be very easily' and cheaply made., and when in use, will ettectually maintain the brake shoe in its proper position.

further obg'ect of the invention is to so construct the brake head that it may be sev cured directly to the-brake beam without the use of castings oi any nature whatsoeverv` 'the entire brake heed proper being a forged one.

-Further objects and advantages of 'the invention will be set Yforth in the detailed deln the accompanying drawing, Figure is a vertical section of a forged brake head constructed ,in accordance with the invention, and ilh ""ating the method of secur- 'ing the br; Lce thereto. llig. 2 is a front elevation oit ne brake head with the brake shoe removed, and lig. 3 is a v view upon 'a 3o 'smaller scale ot' the blank from which the brak head is orin'ed.

Lil numerals corresponding parts in all or ie figures the drawing'.

Reiter ng to thedrawing, the numeral 5 designat brakebeani which is prete 'ably in the 'Corni orf bar. This bea-ni has an iforined therethrough for the reri et or belt l', said rivetiserv d the brake head te the brake f'. brain head consists ol.E an int-e- Vg. 3. This plate has eloni 'ngs 9 formed ii; the opposite ends l and a plurality of smaller openings 1G, formed in the center thereof. By ineans of the proper dies, the plat-e illustrated in llig. is bent into the'foiin illust-rated in ll.. i By referring to Fig. 1, it will be seen that the plate is bent upon itself about at the center of the openings 9. This results in the formation ot a biturcated portion 11 at each end of the brake head. Both thicknesses of the metal atjthe upper portion of the brakehead are bent rearwardly to forni a bow 1Q, the rear thickness of the metal being conl t l l l I l l l l tinued downwardly from said bow, then rearwardly in a horizontal plane to form a securing flange 13. The front thickness of the metal is continued outwardly from the bow 12, then downwardly and then rearwardly to form a retaining lug 14. The front thickness of the metal isthen continued downwardly from the retaining lug 14 to forni a vertical wall 15, the inner face of which is adapted to lie against the face oi one of' the flanges of the I beam. From this wall, the front thickness of the metal is continued outwardly, then downwardly, and then inwardly to form a second retaining lug 1G. I A

The rearniost thickness of the metal is continued from the bifurcated lover end l1 of the' brake head and is bent' inwardly in substantially a horizontal plane to form a retaining flange 17. The rivet or bolt 7 not only passes through the brake beam o but through the retaining flanges 13 ,and 17, said rivet serving to firmly bind the brake head to the brake benin as will be readily undel stood. The retaining lugs M. and 16 receive between them the rearwardly projecting per- Jr'orated ear 1S of the brake shoe 19 which is of the usual and well known construction. A pin or key 2() passes through the openings 10 of the lugs 14 and 1o and through the perforated ear 20, and serves to bind the brake shoe to the brake head. The upper and lower ends oi. the key i2() now lic within the bifurcated, portions 11 of the upper and lower ends of the brake head and the walls 2l of the brake. head lie against the rear Alaces of the brake shoe, adjacent its ends.

rlhe curvature of the face of the brake shoe must be concentric with the' tread ot the wheel, if the brake shoe is to lit snugly against said wheel.. l( istherefore desirable lthat the brake head be capable or" a slight yielding and for this purpose the bowed portion 12 ol' the brake head is provided. lt by reason of sagging of the brake beam below its normal position, the brake shoe assumes a position in which its face is no longer concentric with the tread of the wheel and the brake beam and brake shoe movement of hh Sno@ to randen SW3 @50m he precise. f' A gvnln ns num/e??
